A Study on the Synthesis of 1-Bromododecane catalyzed by Solid Superacid SO_4^(2-)/TiO_2-ZrO_2

本文报道了以自制的固体超强酸 SO2 - 4/ Ti O2 -Zr O2 为催化剂 ,合成溴代十二烷 ,并研究了催化剂用量、反应温度、反应时间、配料比等因素对产率的影响 ,确定了该反应的最佳条件是 :催化剂用量为十二醇用量的 6.5%～ 9%、反应温度 1 1 0℃、反应时间 5h、十二醇与氢溴酸的配料比为 0 .1∶ 0 .1 4。在此条件下溴代十二烷的产率在 67.1 %以上。

This paper reported the synthesis of 1-bromododecane catylyzed by solid superacid SO 2- 4/TiO 2-ZrO 2. The effect of these action factors such as amount of catalyst?reaction temperature? reaction time and meterial ratio on yield ratio is discussed. The proper reaction conditions determined are as follow: amount of catalyst is 6.5%～9% of dodecanol, at 110℃?time 5h?dodecanol: hydrobromic acid=0.1∶0.14(molar ratio). Under these conditions 1-bromododecane yield is more than 67.1%.
